Computer Diagnostics

The diagnostics that are associated with computers can help to identify any problem or failure that computers show when they are having problems.  Diagnostics are used to test out the computer system, which includes both the BIOS and memory, software, and even the hardware that is attached to the computer.

The most common types of problems will occur when your computer is down to very low resources, which can either be a low amount of RAM, or a low disk space.  These conditions are very common, and generally result in your computer running very slow.  This can easily be fixed, all you have to do is defrag your hard drive, and get rid of some programs and files that you no longer use or need.

Almost all types of computer diagnostic software can find and fix just about any problem that you are having.  It normally starts off with a BIOS examination, and goes on from there.  PC diagnostics
software can determine a lot from the BIOS, from the common settings to those that have a major impact on both boot up and performance.

No matter what you do, you should never modify or tamper with the BIOS settings, as it can lead to serious problems.  If you do plan to modify or mess with your BIOS, you should always create a backup first, just in case something goes wrong.  The BIOS settings can be very tricky, although they are responsible for a lot to do with your computer.  If you have never been in the BIOS before, you really shouldn't be modifying anything inside of it.

Depending on the diagnostics program that you are using, there will be several different features available.  Right now, two of the most popular are Norton Systemworks and PC Doctor.  Both of these programs offer full diagnostics software, good for fixing just about any software related computer program you can imagine.  

Once you run the program, you'll be able to select the diagnostic test that you are planning to run.  Some offer you a full system scan, which will scan your entire computer and then display any problems that you having.  After displaying any problems, the software will normally give you an option to go ahead and fix it.  As long as the problem is nothing serious, the diagnostic software can generally fix it.

The more complicated problems, such as hardware failures or hard drive crashes, are a totally different story.  They will require a technician who is very experienced, that can rebuild the hardware.  Diagnostic software can report hardware problems to you, although most of the time it is unable to fix it.

There are other computer diagnostic software that you run after starting the computer or rebooting, that will check everything from BIOS.  These types are great, although the types such as Norton and PC Doctor are by far superior.  They offer far more features, including defragment, cache cleaner, and the option to delete your temporary Internet files.  These features are great to have, especially if you aren't the technical type.

For more reasons than one, computer diagnostic software is the ideal way to find and prevent problems with your computer.  Norton Systemworks offers you Ghost as well, which is the perfect way to back up your data.  You can back up certain files, or just go ahead and back up your entire hard drive.  Systemworks and Ghost are very easy to use, even if you are completely new to computers.  For everything they offer you - computer diagnostic programs are the ideal way to prevent problems before they happen.

The True Score of VoIP User in China, Internet and Mobility Combined in One


Voice over Internet Protocol, or commonly known as VoIP, was first introduced in the North America and European countries and proved to be a "hot item" in the modern communication industry. In addition, the popularity of VoIP system increased further when VoIP system providers introduced the mass-market VoIP services, which allows VoIP subscribers to make and receive voice calls over the traditional PSTN or public switched telephone networks. It resulted to cheaper system maintenance and low monthly subscriptions. In addition, most VoIP system providers are offering unlimited voice calls within domestic applications (areas within the United States, for instance) as well to some other parts of the world, particularly in Canada and selected European and Asian countries for a fixed monthly fee.

If you will take a look on the VoIP's continuous saga on the modern communication industry, you will notice that the main reason for such huge popularity of the system is the cheaper maintenance cost and mobile advantage over traditional telephone lines. VoIP service providers offers monthly subscription cost for as low as 60 percent compared to traditional telephone lines, which makes it cost-effective, especially for small businesses. Hence, if you are maintaining 4 telephone lines and you are averaging $300 per line in terms of monthly subscription cost, you will be able to save as much as $180 per line alone if you will use VoIP instead. That would bring down your telephone bills to $120 per line or a total of $480 compared to $1,200 in all of your 4 telephone lines.

Another noticeable feature of VoIP over traditional telephone networks is its mobile advantage. VoIP allows you to travel anywhere and could still receive and make voice calls using your VoIP phone. For instance, if you have a Detroit phone number and you are traveling in Great Britain, anyone can still make a phone call to you provided that you are connected to the Internet. In addition, your VoIP phone can integrate with other services provided over the Internet such as data exchange, audio conferencing, and video conversation. Such advantage, within cheaper cost, is possible using the VoIP communication system.

The VoIP market is not just expanding on United States, Canada, and European territories alone. In fact, the Asian VoIP market is also making its way as one of the huge-expanding VoIP markets around the world. The revenues of VoIP usage in Asia is projected to reach $10 billion in 2009 from $5.5 billion reported in 2004. Most Asian VoIP users utilize the broadband-based phone system to make international calls, which is said to be a major development in the VoIP market in Asia. Currently, there are approximately 8.7 million existing VoIP lines in use in Asia.

The volume of VoIP users in Asia came from China, which is projected to have over 1 billion regular telephone users and 200 million Internet users by 2010. It is also projected that China will have as much as 400 million mobile users within 2010. However, it is believed that the statistics will decline, following the huge popularity of VoIP in the United States and European territories. Once the Chinese are educated with the advantage and benefits of using VoIP communication system both for residential and business application, market analysts believe that the billion telephone users will drop by as much as 40 percent, based on the projection of VoIP market share increase in Asia.

Currently, the VoIP market in Asia is projected to have a total revenue of $5.5 billion in 2007. About a quarter of these earnings would be spent on Internet Protocol exchanges to open more VoIP lines for Chinese users. The projected revenues of Chinese VoIP market is expected to hit at $7.8 million in 2010, if the subscription in VoIP usage will increase within the projected percentage increase of 13.5 percent annually.

The Asian VoIP market, particularly the Chinese market share, is expected to be as huge as the United States and European VoIP market by 2010. However, the projection will depend on how China and other Asian nations will react on the VoIP communication system. If they learn the benefits of VoIP, the statistics will materialize, and China will go on the VoIP way.
